1. **Problem:** Prepare a discrete frequency distribution table for the data: 12, 21, 21, 3, 9, 3, 6, 12, 13, 21, 15, 22, 3, 6, 9, 9, 21, 22, 15, 13, 15, 9, 15, 6, 15, 13, 6, 9, 13, 22. 2. **Formula and Rules:** A frequency distribution table lists each unique data value and the number of times it occurs (frequency). 3. **Step-by-step:** - Identify unique values: 3, 6, 9, 12, 13, 15, 21, 22. - Count occurrences: - 3 appears 3 times - 6 appears 5 times - 9 appears 5 times - 12 appears 2 times - 13 appears 4 times - 15 appears 6 times - 21 appears 4 times - 22 appears 3 times 4. **Frequency Distribution Table:** | Value | Frequency | |-------|-----------| | 3 | 3 | | 6 | 5 | | 9 | 5 | | 12 | 2 | | 13 | 4 | | 15 | 6 | | 21 | 4 | | 22 | 3 | This table summarizes the data clearly, showing how often each value occurs. Final answer: The frequency distribution table as above.
